帶有複選框的GridView：如何在ASP.Net中獲取選定的行

如何在複選框被選中時獲取gridview的行值。我在按鈕的點擊事件中使用了這段代碼，但它不起作用。帶有複選框的GridView：如何在ASP.Net中獲取選定的行

HTML代碼：

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width="100%" 
     DataKeyNames="ReportId" OnRowDataBound="GridView2_OnRowDataBound" ForeColor="#333333" 
     PageSize="5" Style="text-align: center"> 
     <Columns> 
      <asp:TemplateField> 
       <ItemTemplate> 
        <asp:CheckBox ID="CheckBoxG1" runat="server" /> 
       </ItemTemplate>

C＃代碼：

protected void Button1_Click(object sender, EventArgs e) 
{ 
    foreach (GridViewRow row in GridView1.Rows) 
    { 
     if (row.RowType == DataControlRowType.DataRow) 
     { 
      CheckBox CheckRow = (row.Cells[0].FindControl("CheckBoxG1") as CheckBox); 
      if (CheckRow.Checked) 
      { 

      } 
     } 
    } 
}

我看不出你如何綁定數據，並在那裏爲你的按鈕位置。所以這是工作示例。

<asp:Button Text="text" runat="server" OnClick="Unnamed_Click" /> 
     <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ReportId" Width="100%" 
      ForeColor="#333333" PageSize="5" Style="text-align: center"> 
      <Columns> 
       <asp:TemplateField> 
        <ItemTemplate> 
         <asp:CheckBox ID="CheckBoxG1" runat="server" /> 
        </ItemTemplate> 
       </asp:TemplateField> 
      </Columns> 
     </asp:GridView> 

protected void Page_Load(object sender, EventArgs e) 
    { 
     if (!Page.IsPostBack) 
     { 
      GridView1.DataSource = new RowModel[] 
      { 
       new RowModel { ReportId = "1" }, 
       new RowModel { ReportId = "2" }, 
       new RowModel { ReportId = "3" } 
      }; 

      GridView1.DataBind(); 
     } 
    } 

    protected void Unnamed_Click(object sender, EventArgs e) 
    { 
     foreach (GridViewRow row in GridView1.Rows) 
     { 
      if (row.RowType == DataControlRowType.DataRow) 
      { 
       CheckBox CheckRow = (row.Cells[0].FindControl("CheckBoxG1") as CheckBox); 
       if (CheckRow.Checked) 
       { 

       } 
      } 
     } 
    } 

public class RowModel 
{ 
    public string ReportId { get; set; } 
}

在我的示例代碼中我有考慮手動數據，同時結合GridView控件，因爲你沒有指定你是如何綁定通過DATABSE或沒有你的GridView，但它應該在這兩種方法的工作。我的HTML代碼

<html xmlns="http://www.w3.org/1999/xhtml"> 
 
<head> 
 
<title>Get Checkbox Selected Row Values from Gridview in Asp.net</title> 
 
</head> 
 
<body> 
 
<form id="form1" runat="server"> 
 
<div> 
 
<asp:GridView ID="gvDetails" DataKeyNames="UserId" AutoGenerateColumns="false" CellPadding="5" runat="server"> 
 
<Columns> 
 
<asp:TemplateField> 
 
<ItemTemplate> 
 
<asp:CheckBox ID="chkSelect" runat="server" /> 
 
</ItemTemplate> 
 
</asp:TemplateField> 
 
<asp:BoundField HeaderText="UserId" DataField="UserId" /> 
 
<asp:BoundField HeaderText="UserName" DataField="UserName" /> 
 
<asp:BoundField HeaderText="Education" DataField="Education" /> 
 
<asp:BoundField HeaderText="Location" DataField="Location" /> 
 
</Columns> 
 
<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" /> 
 
</asp:GridView> 
 
<asp:Button ID="btnProcess" Text="Get Selected Records" runat="server" 
 
Font-Bold="true" onclick="btnProcess_Click" /><br /> 
 
<asp:Label ID="lblmsg" runat="server" /> 
 
</div> 
 
</form> 
 
</body> 
 
    </html>

代碼背後：這僅僅是與正確的數據

protected void Page_Load(object sender, EventArgs e) 
    { 
     if (!IsPostBack) 
     { 
      BindGridviewData(); 
     } 
    } 
    protected void BindGridviewData() 
    { 
     DataTable dt = new DataTable(); 
     dt.Columns.Add("UserId", typeof(Int32)); 
     dt.Columns.Add("UserName", typeof(string)); 
     dt.Columns.Add("Education", typeof(string)); 
     dt.Columns.Add("Location", typeof(string)); 
     DataRow dtrow = dt.NewRow(); // Create New Row 
     dtrow["UserId"] = 1;   //Bind Data to Columns 
     dtrow["UserName"] = "SureshDasari"; 
     dtrow["Education"] = "B.Tech"; 
     dtrow["Location"] = "Chennai"; 
     dt.Rows.Add(dtrow); 
     dtrow = dt.NewRow();    // Create New Row 
     dtrow["UserId"] = 2;    //Bind Data to Columns 
     dtrow["UserName"] = "MadhavSai"; 
     dtrow["Education"] = "MBA"; 
     dtrow["Location"] = "Nagpur"; 
     dt.Rows.Add(dtrow); 
     dtrow = dt.NewRow();    // Create New Row 
     dtrow["UserId"] = 3;    //Bind Data to Columns 
     dtrow["UserName"] = "MaheshDasari"; 
     dtrow["Education"] = "B.Tech"; 
     dtrow["Location"] = "Nuzividu"; 
     dt.Rows.Add(dtrow); 
     gvDetails.DataSource = dt; 
     gvDetails.DataBind(); 
    }

代碼Button_Click事件的招投標的GridView

protected void btnProcess_Click(object sender, EventArgs e) 
    { 
     string str = string.Empty; 
     string strname = string.Empty; 
     string edu = string.Empty; 
     string location = string.Empty; 
     foreach (GridViewRow gvrow in gvDetails.Rows) 
     { 
      CheckBox chk = (CheckBox)gvrow.FindControl("chkSelect"); 
      if (chk != null & chk.Checked) 
      { 
       //To Fetch the row index 
       //str += gvDetails.SelectedIndex.ToString(); 

       //To Fetch the value of Selected Row. 
       str += gvDetails.DataKeys[gvrow.RowIndex].Value.ToString() + ','; 
       strname += gvrow.Cells[2].Text + ','; 
       edu += gvrow.Cells[3].Text + ','; 
       location += gvrow.Cells[4].Text + ','; 
      } 
     } 
     str = str.Trim(",".ToCharArray()); 
     strname = strname.Trim(",".ToCharArray()); 
     lblmsg.Text = "Selected UserIds: <b>" + str + "</b><br/>" + "Selected UserNames: <b>" + strname + "</b><br>" + " Education: <b>" + edu + "</b><br>" + " Location: <b>" + location + "</b><br>"; 

    } 
}
